appropriate. (Excessive dust and debris from building
work can contaminate the smoke chamber or heat sensor
and cause problems, it will also invalidate the guarantee).
If it must be installed, first cover it completely, particularly
around the edges, with a dust cover (eg. with the
elasticated cover supplied or a plastic bag), until all
cleaning is finished.
The Alarm must not
be connected when the house wiring
insulation is being checked with high voltages.
i.e. Do not
use a high voltage insulation tester on the alarm.
W
ARNING: Mains operated Alarms should be installed and
interconnected by a qualified electrician in accordance with
the Regulations for Electrical Installations published by the
Institution of Electrical Engineers (BS7671). Failure to install
this Alarm correctly may expose the user to shock or fire hazards.
W
ARNING: The Alarm must be continuously powered 24
hours a day so it is important that it is not on a circuit that can
be turned off by a switch.
Note: BS 5839-6 2004 gives the folowing recommendations regarding the
mains supply to be used in a Grade D system (The Ei141/146
/161RC/166RC Smoke Alarms and Ei144/164RC Heat Alarms can be used
in a Grade D system). The power supply for the Alarms should be derived
from the public electricity supply to the dwelling. The mains supply to the
Alarms should take the form of either:
(a) an independent circuit at the dwelling’s main distribution board, in which
case no other electrical equipment should be connected to this circuit
(other than a dedicated monitoring device installed to indicate failure of the
mains supply to the Alarms); or
(b) a separately electrically protected, regularly used local lighting circuit.
Alarms should be connected on a single final circuit, unless the means of
interconnection is by radio signals (e.g. RadioLINK).
(See BS 5839-6: 2004 for further information)
Note: The Ei Electronics RadioLINK Base Ei168RC (for use with
Ei161RC/164RC/166RC models only) can be used to eliminate
interconnect wiring, make system extensions and provide simple and cost
effective compliance with BS 5839-6: 2004.
4.1 Mounting & Wiring Alarms
1. Select a location complying with the advice in previous
sections (see pages 4-10).
2. Disconnect the AC mains supply from the circuit that is
going to be used.
3. Lift off the wiring cover as shown in Figure 3.
The house wiring must be connected to the terminal block on
the mounting plate as follows:
L: Live - connect to the house wires coloured brown or
marked L.
N: Neutral - connect to the house wires coloured blue or
marked N.
